Benol has addatives to make it mix better
No additives, polymerised or ozidized. Sometimes called blown oil because it is made by blowing air into a vat of hot oil. Blown vegtable oils are used in oil based paints because they bond and harden with age and/or exposure to air. They will also react differantly to various solvents such as gasoline. Not as good a lubricant, but not much worse either.
